thanks all for the thoughts. Ended up replacing all breakers and the
controller and the problem has gone away. sent the controller back to
midnite and came back with no issues so we are assuming it was the breaker.

I might take a clamp on ammeter and check the Classic's battery side
current.
Then maybe turn ON the generator and see what happens to the current
on that line.

I appreciate your contribution to this discussion, but it brings up

Hi Jay. Yes, the OCP you refer to is still there. This particular OCP

Larry, because these MPPT CC's are bi-directional (for efficiencies'
sake), they can convert a large current
at the battery side to a smaller current at the PV side if not adjusted
right. Normally this is just taken
care of and reduced to a bare minimum by the controller watching the
voltages
After the Magnum Inverter/charger samples incoming AC power, they have a slight
delay before starting the charger. Then, they ramp up current slowly.
Even so, how will any current from any other source pass through the breaker
unless the Classic is presenting a load? I suppose something else co

Without knowing exactly what is happening, I would bring a spare Classic

Very strange problem.
While I agree that you should try replacing the 100A breaker, I doubt that
it’s the problem. Why would a breaker trip at low amperage in the morning,
but not trip at noon when the amperage is higher?
At early morning turn-on, the voltage might be too high, but
